Multilayer and Functional Graded Coatings

Dear Colleagues,

Multilayer coatings consist of sublayers with alternative variation in chemical concentrations or crystalline structures. The multilayer-structure is beneficial for improving oxidation resistance, enhancing mechanical properties, reducing internal stress, inhibiting crack propagation, and improving fracture toughness. For example, a columnar crystalline structure formed in a monolithic coating is interrupted due to the distinct characteristics between the sublayers. With the introduced interfaces, multilayer hard coatings have displayed hardness enhancements due to dislocation blocking between interfaces, lattice mismatch, and Hall–Petch effects. Multilayer coatings comprise various assemblies, such as metal/metal, metal/nitride, nitride/nitride, and oxide/metal. This Special Issue on "Multilayer and Functional Graded Coatings" is open to all original research and critical review articles in the relevant topics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Coatings is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
